Abstract: 948,273. Microscopes; testing apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 22, 1962 [May 30, 1961], No. 19500/61. Heading G2J. [Also in Division G1] Optical apparatus which fits on to the draw tube 2 of a microscope and has an eyepiece 3 and is for checking whether the diameter of a test object 15 is within a given tolerance comprises a split-beam optical system including fullyreflecting and semi-reflecting surfaces on the ends of two rhomboid prisms 5, 6 rotatable about an axis 14 whereby the two superposed images may be transversely displaced. Parallel plates 16 and 17, one in each beam, are rotatable about axes 18, 19, respectively, one at least being capable of oscillation with predetermined fixed amplitude, either manually, using a micrometer screw 24, or electrically by means of electromagnets 25, 26 in a transistorised multivibrator-type circuit with a period of <SP>1</SP>/ 2 -5 seconds. If the two images are initially displaced by the diametral distance so that diametrically-opposite points are approximately coincident, oscillation of the plate 17 will cause transverse oscillation of the associated image which, if below the given tolerance, will at one instant be observed to coincide with the other. Failure to achieve coincidence indicates a toolarge diameter. The amplitude of oscillation may be varied, for any desired tolerance, by adjusting the separation of the stops 22, 23.

Title: Improvements in or relating to electrical apparatus for distance measurements
IPC: G01S7/06
Filed: 1938-07-02
Abstract: 511,093. Locating objects by reflected waves ; oscillographs. SPERRY GYROSCOPE CO., Inc. July 2, 1938, No. 19620. Convention date, July 3, 1937. [Class 37] Apparatus for measuring the distance between a radio transmitter and a reflecting body has the intermittent emission of the radio transmitter controlled by a relaxation oscillation generator which is also connected to a pair of oscillograph deflecting plates and brings the beam on to the screen during discharge of the condenser. The line traced during each discharge is cut off by the radio receiver, since the reflected impulse is applied to the control grid of the oscillograph. The vertical trace is associated with an altitude scale in logarithmic units. As shown, the discharge of condenser 53 in the relaxation generator 49 applies a potential across resistor 55 which potential takes the bias from the grid of the oscillator valve 47 and permits a short emission from the directive aerial 56. Simultaneously the oscillograph beam is brought to the bottom of screen 61 and rises as the voltage across resistor 55 falls. The incoming reflected waves on receiver 68 charge condenser 73 through diode 71, and this potential is applied to cut off the oscillograph beam. When condenser 73 is discharged the beam is returned to its " on " position above the scale 67. The resistor 55 can be adjusted to increase the sweep of the oscillograph beam, thus giving scale indications in ten, one hundred or one thousand-foot intervals. The Specification as open to inspection under Sect. 91 comprises, Fig. 1 (Cancelled), wherein an oscillator 5 and directional aerial 7 are intermittently energized from a source 2 by a motor 8 that drives a bar 11 bridging contacts 12. The motor 8 also drives a generator 15 feeding phase-displaced potentials to the pairs of deflecting plates 23, 25 of a cathode-ray tube 19, the supply voltages for which are taken from potentiometer 33. The receiver aerial 29 is also directional and obtains a direct pulse each time the transmitter circuit is closed. The control grid 32 of the tube 19, which is normally negatively biassed, thereby allows a spot 37 to appear on the screen, Fig. 2 (Cancelled), and a further spot 371 when the reflected wave is received. The time interval between spots 37, 37<1> is expressed in feet on scale 40. The " zero " spot 37 is adjusted by gearing 38, 39. By changing the ratio of gearing 14, or by connecting an harmonic generator at 45, the scale indications can be multiplied as desired. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the flow control and measurement of granular material
Inventor: RICHARDSON ALAN HALSTEAD
IPC: G01G13/00
Filed: 1962-05-22
Abstract: 999,174. Automatic feed and discharge weighers. UNION CARBIDE CORPORATION. May 22, 1962, No. 19654/62. Heading G1W. In an automatic feed weigher for granular material e.g. lime receptacle 9 (Fig. 1) having an invertible portion 23 is supported on one end of a weigh beam 17 pivoted on a shaft 19. A deformable metallic resistant 41 e.g. steel (Fig. 3 not shown) and a damper 46 are connected between the other end of the beam and a pedestal 1. The receptacle portion 23 is moved, by means of a double acting piston 43 actuated by forced air and controlled by a solenoid valve 33, to open or close the receptacle discharge outlet. An electrical vibratory feeder 11 when actuated causes hot lime to flow from a Kiln 3 and when deactuated causes the flow to cease. Switch A coupled to the deformable resistant 41 is adjusted to close when the receptacle load attains a predetermined weight and thus connect a voltage source 45 to timing relays 47, 49. Relay 47 then deactuates the feeder 11. Relay 49 subsequently causes the solenoid valve 33 to introduce forced air to conduit 40 whereby the receptacle empties on to conveyer 50. After a time interval sufficient to empty the receptacle the relay 49 causes valve 33 to introduce air to conduit 39 and shut off conduit 40, and the receptacle is thus closed. Timing relay 47 delays reactuation of the feeder 11 until sufficient time has lapsed for the closure to have taken place. The cycle is then repeated. The switch A may also be connected to a counting mechanism to totalize the amount of lime withdrawn. Instead of the deformable metallic resistant 41 there may be a pneumatic or hydraulic load cell.

Filed: 1946-07-02
Abstract: 621,056. Controlling air supply to locomotive furnaces. MANSFIELD, V. July 2, 1946, No. 19778. Convention date, July 30, 1945. [Class 51 (i)] In a locomotive having elongated inlets 14 on each side of the firebox through which air is supplied to the ashpan due to the motion of the locomotive, a series of transverse baffles 22 are arranged in each inlet to prevent substantial fore- and-aft movement of air therein and to deter the formation of eddy currents. The spacing between the baffles may increase from front to rear to maintain the air flow proportional to the furnace volume above each grate section, and the effective height of the baffles may also increase from front to rear so that each baffle will catch and deflect the appropriate amount of air for the space between it and the preceding baffle. In one form, Fig. 8, the baffles are arranged in troughs 24 on each side of the ash pan 10, each trough comprising a fixed portion 40, Fig. 10, and a hinged section 42 held in position by latches 48. A longitudinal baffle 56 is secured to the underside of each mud ring 16 and serves to deflect the airstream upwardly through apertures 60 and inwardly towards the centre of the grate 6. In a modification, Fig. 11 (not shown), the baffle 56 is replaced by a number of angularly disposed baffles 57. The Specification as open to inspection under Sect. 91, also describes a construction in which air is supplied to the troughs through manifolds, Fig. 12 (Cancelled), arranged on each side of the firebox and each comprising a casing with a number of vanes 82-96. The lower curved ends of the vanes may constitute or be aligned with the baffles 22. The spacing between the vanes increases from front to rear and top to bottom as shown. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to controls for motor vehicles
IPC: F16D23/12
Filed: 1958-06-20
Abstract: 872,657. Clutch control. HADEKEL, R., and HERBERT, J. R. June 10, 1959 [June 20, 1958; Dec. 19, 1958], Nos. 19833/58 and 41057/58. Class 80 (2). Depression of a throttle-control pedal beyond a predetermined position allows a friction clutch between the engine of a motor vehicle and the gear-box to engage, and return of the pedal to its initial position under spring pressure disengages the clutch. The clutch 1 between the engine shaft 4 and the gear-box input shaft 5 is shown in Fig. 1 in its disengaged position. The accelerator pedal 3 is pivoted at 28 and is connected by a link 29 to a lever 30 pivoted at 31. The throttle valve 2 is rigid with a lever 33 which is connected by a link 32 incorporating a lost-motion slot 37 to lever 30. A spring 38 biases the throttle valve 2 towards its closed position. An adjustable stop 39 is provided to give a slow-running position. The clutch plates 11, 9, 13 are urged into engagement by springs 16 and are disengaged by sliding a member 22 along shaft 5, the member 22 co-operating 'through a bearing 21 with levers 23 pivoted at 19 to the plate 13. The member 22 is moved to the left under the pressure of a lever 25 pivoted at 26 and in operative engagement with a rod 40 sliding in guides 41 and connected to the lever 30, and with the pressure removed is moved to the right by the action of springs 16. An adjustment member 42 is provided. By depressing the pedal 3 the throttle valve 2 is opened and the rod 40 moves to the left relieving the pressure upon lever 25 and allowing the clutch to engage. A spring 34 returns the pedal 3 to its initial position and disengages the clutch. The rod 40 may be replaced by a tension spring or by a flexible cable or by a push rod suitably placed between the levers 25 and 30, or a flexible cable may be inserted between the lever 30 and the link 40 so that the return position of the lever 30 is not limited by the clutch but by a stop 35. In a modification, Fig. 2, the accelerator pedal is connected to the throttle through link 32 and to the clutch control lever 25 through links 40<SP>1</SP>, 43 and a flexible cable 45. The link 43 is pivoted at 44 to a member 46 which is slidable in guides 47 and 48 and may be put in one of three operating positions by a hand control 50. In the first position the throttle opens to a greater extent than normal before the clutch engages and is useful for a cold engine; in the centre position the device operates as with Fig. 1 and in the third position the clutch may engage at a smaller than normal throttle opening or may be set so that the clutch is engaged when the accelerator pedal is in its undepressed position, i.e. the clutch control is overridden.
